Column Flotation of Copper 911metallurgist

A column flotation system was designed to conduct release analyses of a very finely disseminated, stratiform, copper ore from the Denali Copper Prospect, Alaska. Chalcopyrite is finely disseminated in a carbonate matrix and pyrite is disseminated in both the chalcopyrite and gangue, requiring grinding to 20 microns for adequate liberation.

Column Flotation Cells Mineral Processing & Metallurgy

Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable of high selectivity.

flotation of silica from iron ore samples. The first notable industrial success of flotation columns was by Column Flotation Company of Canada on moly cleaning at Norandas Les Mines Gaspé (Cienski and Coffin, 1981; Coffin and Miszczak, 1982). Today column flotation has become . an accepted means of froth flotation

Application of Flotation Column on Flotation of Copper Ore

Due to the complex mineral composition in the ore, a joint process of flotation and gravity concentration was used to process the ore. Beneficiation results show that, a tin concentrate and a tin middlings can be obtained, assaying 37.12% Sn and 4.95% Sn at the recovery of 40.91% and 22.96% respectively; a copper concentrate assays 15.21% Cu at a recovery of 78.21%, when the raw material assays 0.42%

Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Flotation of fine ores. Flotation of fines requires special features higher energy collection with smaller bubbles to guarantee a good recovery; a less turbulent regime / good slurry distribution to avoid bypass; and a fluid, thicker and more selective froth to generate a better product quality.

Column Flotation Eriez Flotation Division

Eriez has more than 900 Column Cells operating worldwide. The Eriez Flotation Division has supplied more than 900 flotation columns throughput the world in mineral concentrating and purification applications that include iron ore, base metals, gold, industrial minerals, fertilizers (phosphate and potash), energy (coal and oil sands) and specialty applications such as oil/water separation.

Process Description and Technological Phenomena of A ColumnFeatures of A ColumnAeration The Most Essential Aspect of ColumnsApplication of ColumnsReferencesThe column is fed with ore pulp in its upper third portion and, at the lower section, air is injected at high velocities. This causes the pulp to flow down against a swarm of rising air bubbles. This counter current flow promotes the suspension of particles in the pulp. In addition, the energetic injection of air provides for the generation of small bubbles and promotes the contact of these bubbles with the ore, leading to the collection of hydrophobic particles.The loaded bubbles ascend andGet Price
